Title:
METHOD OF RECYCLING WATER-SOLUBLE PROCESSED LIQUID, APPARATUS FOR RECYCLING WATER-SOLUBLE PROCESSED LIQUID, METHOD OF TREATING OIL-CONTAINING WASTEWATER AND APPARATUS FOR TREATING OIL-CONTAINING WASTEWATER
Document Type and Number:
WIPO Patent Application WO/2006/090859
Kind Code:
A1
Abstract:
It is intended to provide a method of efficiently separating oily components from an oil-containing wastewater to such a level as allowing water discharge without resorting to pH adjustment or complicated temperature control, and a method of obtaining a microorganism capable of decomposing oils which is to be used in the above method. Namely, an oil-containing wastewater is treated with the combined use of a microorganism capable of decomposing oils with a gelling/solidifying agent for mineral oils and active carbon. The microorganism as described above is obtained by maintaining a used water-soluble mold release agent for hot forging in a container at an elevated pressure for several days.
